Conference paper


The first attempts to disintegrate concretions extracorporeally using piezoelectric techniques date from the late fourties (Berlinicke and Schennetten 1951; Coats 1956; Lamport et al. 1950; Mulvaney 1953). These authors achieved a slight disruption of concretions by applying sound waves at intensities of about 5 W/cm2 over a period of up to 30 min.
